anytime i am making straight seams, with no curves or insets, i quilt with the serger...super fast, perfect quarter inch seam and when pressed, the thread gives you just the teeniest bit of support to a great looking seam...i sew with my serger set to approx 1.5 length away from each other so that it looks like a normal seam on the outside. Tip** only one thread really shows in the 'ditch, so use gray for three cones and your 'fashion' color for that one needle thread on the left side.... much less thread to buy... i buy beige, white, black and 2 shades of gray in sets of three, everything else is 1 cone per fashion color...one of the neutral sets will blend just fine with almost anything
